Taking the pressure equipment for mold forming as an example, the parallelism between the movable plate and the fixed plate in the pressing process is the most important factor related to the quality of the mold forming. There are two main indicators that affect the parallelism of the two plates. One is the movable plate and the fixed plate. The flatness of itself is guaranteed by the plate material and mechanical processing. The second is the influence of the guide rail gap. During the movement of the movable plate along the guide rail, the guide rail gap has a great influence on the parallelism between the movable plate and the fixed plate. In practice, a very tight clearance fit is often used, which increases the offset wear of the movable plate during operation, resulting in poor operation, and finally affects the parallelism

Embodiment Construction
[0015] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:
[0016] See attached Figure 1~4 As shown, this kind of compensation device for correcting the parallelism between two relatively moving flat plates, the positions of the two relatively moving flat plates are up and down relative to each other, and are respectively a fixed flat plate 2 and a movable flat plate 5, and the fixed flat plate 2 is fixed on the machine. On the frame, the movable flat plate 5 is installed on the bearing structure of the slider. The bearing structure of the slider is rectangular, and the movable flat guide rails 6 are installed at the four corners of the bearing structure of the slider. The movable flat guide rails 6 can slide along the bed guide rail 4, so that The movable plate 5 and the fixed plate 2 can move relative to each other. A set of parallel shaft assemblies are respectively installed at t...

The invention discloses a compensating device for correcting parallelism degree of two flat plates in relative motion. The compensating device is characterized in that parallel shaft components are mounted longitudinally and transversely on a fixed flat plate (2) respectively, and fork-shaped members (16) accurately uniform in opening direction are arranged at two ends of each parallel shaft component, correcting wheel components are mounted at corresponding positions right below the fork-shaped members (16) of the parallel shaft components corresponding to a movable flat plate (5); when the movable flat plate (5) moves along a guide rail (4), openings of the fork-shaped members (16) contact with correcting wheel bearings (12) to enable the fixed flat plate (2) and the movable flat plate (5) to enter a compensation correcting process. By the compensating device, the parallelism degree of the flat plates in the process of press-fitting is increased greatly and can be increased to 0.02mm from 0.1mm. The compensating device is simple in structure and low in manufacturing cost.
Description
technical field [0001] The invention relates to a compensating device for correcting the parallelism between two relatively moving flat plates, which belongs to the technical field of product structure. Background technique [0002] The parallelism between two plates moving up and down relative to each other is a key technical index in some engineering applications. Taking the pressure equipment for mold forming as an example, the parallelism between the movable plate and the fixed plate in the pressing process is the most important factor related to the quality of the mold forming. There are two main indicators that affect the parallelism of the two plates. One is the movable plate and the fixed plate. The flatness of itself is guaranteed by the plate material and mechanical processing. The second is the influence of the guide rail gap. During the movement of the movable plate along the guide rail, the guide rail gap has a great influence on the parallelism between the mova...
